What is ISW ?
ISW (In-System Writer) is a process of updating the control programs stored in flash ROM mounted on various
control boards in a Konica digital copier without isolating the boards from the copier. Running ISW enables you
to upgrade control programs without replacing the boards and maintain the boards during their replacement.
Tools av ailable f or running ISW include ISW Trns (PC software), which connects a personal computer (PC) to the
digital copier, and ISW Tool, which is a dedicated tool using EPROM.
These tools can be plugged into the ISW connector of the digital copier to directly update the control programs in
flash ROM assembled in the unit.
This chapter focuses on instructions on setting up the 7075 to run ISW. For how to run ISW Trns and ISW Tool,
refer to Konica ISW (In-System Writer) Service Handbook.
Note: Procedures for using ISW Tool to update ROM data in Konica ISW (In-System Writer) Service
Handbook are divided into three types by copier model. For this unit, see “Updating the Type C
Model.”

SETUP
[1] ISW-compatible boards
The 7075 allows ROM data residing on the
following boards to be updated via ISW Tool:
- Graphics control board
- Printer control board
- Operation control board
- ADF control board
- Video I/F board
The ROMs of other boards than the above need
to be replaced.

[2] Data flow
PC/ISW Tool Graphics control Operation control board
Printer control board
ADF control board
Video I/F board
Important Note:
The availability of the Graphics control board is
prerequisite to updating ROM data on other boards.
[3] Ready up the copier to start an ISW
transfer
1. Transfer modes
The copier supports three transfer modes as
described below.
2. 25 mode
The 25 mode works only where the copier has
both the graphics control and operation control
programs installed.
(Some parts of HELP+CHECK mode are used
to update the operation control program in 25
mode.)
- Power-on mode
If the copier does not have the graphics control
program installed, its writing to the copier is
enabled when the copier is turned on. Because
the graphics control board controls the power
supply to the operation control board, nothing will
appear on the operation LCD even though the
operation control program has been installed on
the copier.
- HELP + CHECK mode
Turning ON the copier with HELP and CHECK
puts it into the HELP + CHECK mode. If the copier
has the graphics control program installed, but
not the operation control program, the 25 mode
would not launch. This mode is specifically
maintained to enable ISW in this situation.
